Abstract
Sodium fluoroantimonate single crystals of monoclinic NaSbF 4 and orthorhombic Na 2SbF 5 of optical quality have been grown from saturated solution at constant temperature (305 K) by slow evaporation technique. The grown crystals were confirmed by chemical and X-ray analysis. Vickers microhardness measurements have been carried out on these crystals. The hardness values of NaSbF 4 and Na 2SbF 5 single crystals are about 1.2 GPa and 1.15 GPa respectively. The dielectric constant (ϵ') and dielectric loss (Tan δ) were determined as a function of frequency in the range from 100 Hz to 100 KHz at room temperature. It was found that both the dielectric constant and dielectric loss decrease with increase in frequency. The values of dielectric constant of NaSbF 4 and Na 2SbF 5 at (100) orientation for 100 KHz are about 11.40 and 14.15 recpectively.
